Dentist in Spring Texas – How Dentist put Crown
A dental crown is a tooth-shaped cap, which is placed over a tooth. This is usually done to cover the tooth and restore the shape of the tooth. A crown, after being cemented, will encase the visible portion of the tooth, which is above the gum line. This article prepared by experts at Vita Dental Springs will tell you how a dentist places the crown on your tooth.
Visit the dental office
Crowing take places in two visits. In the first appointment, the dentist will prepare the tooth and take an impression. A temporary crown may also be placed. When the patient goes in for the second visit, this is when the crown will be fitted onto their tooth.
The First Appointment
At the start of the appointment, the dentist will numb your tooth and the surrounding tissue. However, if the tooth has undergone a root canal, numbing will not be required. However, the surrounding gum tissue will still be numbed to ensure you remain comfortable throughout the operation.
Shaping the tooth
At the appointment, a portion of the tooth will need to be removed. This is because all crowns have a certain minimum thickness for them to be viable. It ensures they have enough strength to last for many years. For most crowns, this minimal thickness is about two millimeters. The trimming will often take place on all sides of the tooth.
During trimming, any decayed section of the tooth may be removed as well. If there is any loose filling material, it will also be removed. Because of this, some huge chunks of your tooth may need to be trimmed. In such an instance, the crown is going to be thicker in those areas. Besides trimming, the tooth needs to be in a tapered shape. This will ensure that the crown can be slipped over the tooth.
Taking of the impression
After the dentist is done shaping the tooth, he, or she will need to make a copy of it using a dental impression. This is done using two different processes. One of them is a conventional process where a paste or putty-like material is used.
An impression of the opposing teeth will also be taken. Besides that, a bite impression is taken. This will help to determine how the patients bite the teeth together. The impression is sent to a laboratory where it is used to make a plaster cast for the fabrication of the crown.
The other technique used to take dental impressions is an optical machine. It utilizes a small camera. The image taken by the camera is analyzed using CAD equipment and with the dentist’s oversight, the designed is fabricated.
Placing a temporary crown
If you will need to wait for the crown to be fabricated, the dentist will give you a temporary crown. This crown protects the trimmed tooth and keeps it from shifting. It is often made of plastic or metal. It will be fitted using temporary cement to make it easy to remove at your next appointment.
Choosing the shade
If you choose a crown made of porcelain, the dentist can choose the right shade for your teeth. He or she will come with a few pieces of different colors. The sample will be held against the space the crown will occupy. He or she will then use that to determine the most natural looking color.
The Second Appointment
Once the fabricated crown is made, your dentist can now cement it in place.
Taking out the temporary crown
To do this, the dentist will first numb the tooth. However, this may not always happen. It is painless to have the crown fitted. The crown will be removed and the remnants of the temporary cement are washed off.
Evaluating the crown
Before cementing the new crown, the dentist will ensure that it fits and looks right. During this evaluation, they will check the fit of the tooth. The crown will be seated on the tooth and inspected that it fits. If the crown is not perfect, it will be removed and adjustments made. This will be repeated several times until he or she feels that the tooth is in a perfect position.
The appearance will also be checked. This is especially so in cases where the tooth is a frontal tooth. The dentist may even hand you a mirror to help him in his assessment. After he or she is sure everything is okay, the procedure will continue.
After you agree that everything looks good, your crown will be cemented. Firstly, the dentist will place dental cement inside the crown and then place it on the tooth. After waiting a few minutes, the dentist will use a dental tool to scrape away excess cement extruded from around the edges of the crown. After that, he will give you some instruction on how to care for the crown. You can now go home.
